Nowadays, many sewage treatment enterprises are still using polyaluminum chloride, polyaluminum ferric chloride, ferric chloride, lime, anionic polyacrylamide, cationic polyacrylamide and other traditional water treatment agents. These traditional water treatment agents not only use a large amount, but also have bad sludge dewatering effect, corrosion equipment and other drawbacks. What are the alternatives to these traditional water treatment agents?
One. Comparison of the amount added:
Due to the significant effect of the sludge conditioner, the dosage is greatly reduced, under normal circumstances, the price of 4 kg per ton of absolute dry sludge can be, and the traditional iron salt lime conditioner, the dosage is often greater than 200 kg.
Two, conditioning aging comparison:
The effect of sludge conditioner is significant, the effect is rapid, and the dosage is small, so the conditioning time is very short. It usually takes about half an hour to complete. The traditional iron salt lime conditioner needs to be added separately, and needs a certain amount of time, generally more than 1 hour.
Three. Comparison of processing capacity:
Because the amount of sludge conditioner is greatly reduced while improving the dewatering effect, the amount of sludge treated by a single press filtration cycle is also much higher than that of the traditional iron salt lime conditioning
Four, From the above comparison can be seen:
Sludge conditioner has more obvious advantages than traditional pharmaceutical: convenient filling, easy maintenance, reduce loss, environmental reuse. At the same time, due to the small amount of addition, the distribution cycle of sludge conditioner is greatly extended. Because the agent is environmentally friendly, non-toxic and non-corrosive, the loss of equipment is greatly reduced, and the filter cloth should not be blocked: the mud cake does not introduce harmful substances, and can meet a variety of utilization methods.
